All three strings will lose some tension initially then stabilize. The soft feel of them takes the 'metallic' feel out this frame but really lets you swing out, and all seem to pocket the ball nicely. I've gotten about 14 hours of play out of XCEL and although notched, is not broken yet.

TF E-matrix would also be a good choice but is not durable at all

I have the RD-7 and the RDX-500 MP. You can use your same RD-7 set-up on the RDX-500 MP, but go up on the tension, both on crosses and mains, by 5 pounds, at least... The RD-7 likes lowish tensions; the RDX-500 MP not so much...

Edit: I'd use the same tension as on the RDX-500 MP on the RQS-11 and/or TI-80...

Actually I have been using high 70s in my RD-7 for the last ten yrs. I dont think I should use even higher number in the rdx500. I am really looking at a better quality string to replace my cheap nylon as well.
